A score usually on a scale of 1 to 9 derived from hip height measurements and age. This score is used to classify skeletal structure and should remain constant throughout the animal’s life.

Hip Heights (inches) and Frame Scores for 5-21 Month-Old Bulls = -11.548 + (0.4878 x Ht) – (0.0289 x Age) + (0.00001947 x Age2) + (0.0000334 x Ht x Age), where Age = days of age.

Hip Heights (inches) and Frame Scores for 5 - 21 Month-Old Heifers = -11.7086 + (0.4723 x Ht) – (0.0239 x Age) + (0.0000146 x Age2) + (0.0000759 x Ht x Age), where Age = days of age.
